  Hello dear members
  
  I get confused about selection mesh methods. Especially between tethrahedral and hex dominant.
  
  What is the way of thinking on choosing them?
  
  When should I use tetrahedral?
  
  Can we make an interpretation?
  
  Thanks

  10 node tetrahedrals are good elements (not 4 nodes) - of course you need more tets than hexahedral to cover the same volume (say a cube), so you do get more elements with tets. On the other hand it is not possible to mesh any/all geometries just with only hexahedrals, but if you can then use them.
  
  Read through this from Erke:
